[Python Programming](https://help.datasciencedojo.com/migration/python-programming?hsLang=en) # What do you understand by reindexing in pandas? Reindexing is the process of conforming a dataframe to a new index with optional filling logic. If the values are missing in the previous index, then NaN/NA is placed in the location. A new object is returned unless a new index is produced that is equivalent to the current one. The copy value is set to False. This is also used for changing the index of rows and columns in the dataframe.   - [Data Science Bootcamp](https://help.datasciencedojo.com/migration/data-science-bootcamp?hsLang=en#main-content) - [Certificate](https://help.datasciencedojo.com/migration/data-science-bootcamp?hsLang=en#certificate) -
